【 摘 要 】

The uniqueness of the urban physiographic landscape could share advantage as well as constraint for the sake of urban water availability. Physiography landscape of urban area will slightly affect the ability of a city in providing water needs of urban dwellers. An alternative solution to resolve the problem is rainwater harvesting. Semarang is one of secondary cities, faces various problems such as ground water scarcity, land subsidence, flood, and drought. Water resilience problem of Semarang would become more severe when development activities do not pay attention to 2 kinds of landscapes: social and physiography dimension. This study aims to examine the distribution and characteristics of landscape physiography associated with social condition, considering appropriate form of rainwater harvesting application. The basic methods used are spatial analyses and combined with non-parametric statistical technique based on questionnaires. Landscape physiography variables embrace various aspects of altitude, slope, geology, soil, ground water potential, landslide, flood, and land subsidence. While social variables involve several aspects of community attitudes, gender, education and income. The results shows that the application of rainwater harvesting needs to consider physiographic landscape together with social profile to ensure and support water resilience of urban areas.
